Opportunistic Salpingectomy at the Time of Benign Laparoscopic Hysterectomy: Assessment of Possible Complications and Histopathological p53-Signatures.

Introduction: The aim of this study is to assess the prevalence of tubal histopathological abnormalities (serous tubal intraepithelial carcinoma STIC and p53 signatures) and the prevalence of perioperative and postoperative complications related to opportunistic laparoscopic salpingectomy in a low risk population.

Materials and Methods: In this observational prospective cohort, prophylactic bilateral salpingectomy during benign laparoscopic hysterectomy was systematically performed in 100 consecutive women. Peri- and postoperative complications were registered. Duration of salpingectomy and post-salpingectomy blood loss were also measured. Histopathological and immunohistochemical analysis with anti-p53 antibody were performed on the whole fallopian tubes according to a specific and validated protocol.

Results: Laparoscopic salpingectomy was always possible without any peri- or postoperative complication attributable to the salpingectomy itself. The mean duration was 428 seconds (354 - 596) and the blood loss was 9 cm 3 (2 - 15). Using histopathological and immunohistochemical assessment with anti-p53 antibody on 199 fallopian tubes (99 bilateral salpingectomies and one unilateral salpingectomy because of previous salpingectomy for ectopic pregnancy), there was a prevalence of 5.52% (11/199) of p53 signatures. No STIC were observed and no associated cancer.

Conclusions: Laparoscopic salpingectomy is both feasible and innocuous during benign hysterectomy. Meticulous histopathologic examination of the tubes may reveal specific abnormalities.
